FAQ Central HEPA Air Purification System
According to the EPA: “Of primary concern from a health standpoint are invisible, respirable particles, which have a higher probability of penetrating deep into the lung and causing acute or chronic effects.” The ability of HEPA filter media to capture at least 9,997 out of every 10,000 0.3 micron particles makes them far superior to other types of filters.
Studies have shown that air cleaners attached to the main ventilation system are generally much more effective. Plus you would need to buy a number of these devices and put them throughout your home. That would be costly, noisy and intrusive.
Electronic air cleaners start off with lower efficiency and their efficiency drops way off as the collection plates get dirty. Most models require frequent, ongoing maintenance. The efficiency of HEPA filter media remains at or above 99.97% throughout the filter loading cycle.
These low energy-consumption blowers overcome the resistance of the CAP filter media and ensure that the HVAC system airflow remains at normal levels.
To maintain peak performance, the inexpensive first stage pre-filter should be replaced monthly and the intermediate filters when the amber ‘change filter’ lamp illuminates. UV and UV Plus lamps should be replaced annually, and the HEPA filter every 3 to 4 years. Contact your installing dealer for an annual replacement filter and lamp kit.
